ABSTRACT

A new and distinct cultivar of Kalanchoe plant named ‘Segula’, characterized by its numerous, large, and light red purple-colored flowers; upright and uniform plant habit; freely branching growth habit; dark green and glossy leaves; early flowering; and excellent postproduction longevity.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Kalanchoe blossfeldiana cultivar Segula.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofKalanchoe plant, botanically known as Kalanchoe blossfeldiana, andhereinafter referred to by the name ‘Segula’.

The new Kalanchoe is a product of a planned breeding program conductedby the Inventor in De Lier, The Netherlands. The objective of thebreeding program was to create new freely-branching and freely-floweringKalanchoe cultivars with attractive foliage and flower coloration.

The new Kalanchoe originated from a cross made by the Inventor in 1998of the Kalanchoe blossfeldiana cultivar Lokon, not patented, as thefemale, or seed, parent with the Kalanchoe blossfeldiana cultivar Gede,not patented, as the male, or pollen, parent. The cultivar Segula wasdiscovered and selected by the Inventor as a flowering plant within theprogeny of the stated cross in a controlled environment in De Lier, TheNetherlands.

Asexual reproduction of the new Kalanchoe by terminal vegetativecuttings taken at De Lier, The Netherlands, since 1998 has shown thatthe unique features of this new Kalanchoe are stable and reproduced trueto type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Segula has not been observed under all possibleenvironmental conditions. The phenotype may vary somewhat withvariations in environment such as temperature, daylength and lightintensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined tobe the unique characteristics of ‘Segula’. These characteristics incombination distinguish ‘Segula’ as a new and distinct cultivar:

1. Numerous, large, and light red purple-colored flowers.

2. Upright and uniform plant habit.

3. Freely branching growth habit.

4. Dark green and glossy leaves.

5. Early flowering.

6. Excellent postproduction longevity.

Plants of the new Kalanchoe can be compared to plants of the femaleparent, the cultivar Lokon. In side-by-side comparisons conducted by theInventor in De Lier, The Netherlands, plants of the new Kalanchoediffered from plants of the cultivar Lokon in the followingcharacteristics:

1. Plants of the new Kalanchoe were larger and more vigorous than plantsof the cultivar Lokon.

2. Plants of the new Kalanchoe had larger leaves than plants of thecultivar Lokon.

3. Flower color of plants of the new Kalanchoe was lighter red purplethan flower color of plants of the cultivar Lokon.

Plants of the new Kalanchoe can be compared to plants of the maleparent, the cultivar Gede. In side-by-side comparisons conducted by theInventor in De Lier, The Netherlands, plants of the new Kalanchoediffered from plants of the cultivar Gede in the followingcharacteristics:

1. Plants of the new Kalanchoe were more uniform in growth habit thanplants of the cultivar Gede.

2. Flower color of plants of the new Kalanchoe was light red purplewhereas flower color of plants of the cultivar Gede was yellow.

Plants of the new Kalanchoe are similar in flower color to plants of theKalanchoe cultivar Keruna, not patented. In side-by-side comparisonsconducted by the Inventor in De Lier, The Netherlands, plants of the newKalanchoe differed from plants of the cultivar Keruna in the followingcharacteristics:

1. Plants of the new Kalanchoe were more vigorous than plants of thecultivar Keruna.

2. Plants of the new Kalanchoe had larger flowers than plants of thecultivar Keruna.

3. Flower color of plants of the new Kalanchoe was softer red purple anddid not fade as readily as flower color of plants of the cultivarKeruna.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The RoyalHorticultural Society Colour Chart except where general terms ofordinary dictionary significance are used. Plants used for theaforementioned photograph and for the description were grown during thespring in De Lier, The Netherlands, in a glass-covered greenhouse.During the production of the plants, day temperatures ranged from 19 to26° C.; night temperatures ranged from 20 to 21° C.; and light levelsranged from 10,000 to 50,000 lux. Unrooted cuttings were directly stuckin 12.5-cm containers and received long day/short night conditions (morethan 14 hours of light) for about 2 weeks; plants then receivedphotoinductive short day/long night conditions (minimum 14 hoursdarkness) until flowering. Plants were about 15 weeks old from anunrooted cutting when the photograph and the description were taken.
